Cuba says second COVID-19 vaccine Soberana 2 boasts 91.2% efficacy

Cuba says it has a total of five candidate vaccines in the pipeline, with Abdala and Soberana 2 expected to be quickly authorized for emergency use by local regulators and sent up for approval to the World Health Organization.

Both vaccines are “low” tech, meaning they use a traditional approach deploying a part of the virus’s spike protein which helps the virus enter and infect cells, to build up the immune system.
